5. Use the LocalSystem account for MSSQLServer and SQLServerAgent services.

You can change it later to an appropriate domain account, once you have
successfully installed SQL Server. Using the LocalSystem account helps
to reduce potential SQL Server installation problems.

6. Close the Service Manager icon in the taskbar.

Microsoft recommends closing the Service Manager icon in the taskbar because it may cause SQL Server Setup to fail.

7. Stop some services, which can cause installation failure.

Because some services may cause installation failure of SQL Server due
to a Windows NT/2000 logon failure or time out, you should stop these
services before installing SQL Server 2000, and then restart them once
SQL Server has been successfully installed. Stop the following services:

IIS - Internet Information Server

Exchange Server

SNA Server

Disk Keeper

SNMP Service

Anti-virus software (such as McAfee)

Backup products (such as ARC Server)

8. Close all extraneous programs that are running.

Because extraneous programs use some system resources, it is a good idea
to close all extraneous programs before installing SQL Server 2000. Be sure
that there are no any programs on the taskbar except the Setup application.

If you cannot install MS DTC on a server with multiple network cards or
SPX installed, uninstall one of the network cards or SPX, and then retry
the SQL Server Setup.

10. You can get the error during installation of SQL Server 2000
Personal Edition or SQL Server 2000 Desktop Engine if there is a
previous edition of SQL Server 7.0 Desktop Edition or MSDE 1.0
installed.

The cause of this error is that there is not enough system memory to run all of the necessary SQL scripts. You should have at least 48 Mb
of RAM (for Windows 9x) rather than the 32 MB of RAM as stated in SQL Server Books Online.

11. Before reinstalling SQL Server 2000 after a failed install,
delete the following registry entries:
